Air behaves differently in a sealed Gulf building. We publish what that changes.
Most indoor air research comes from somewhere with a different climate and a different kind of house. We read it, work out what carries over, and write up what we find — including when it constrains what we sell.
Lines of enquiry
Each series follows one question. The colour marks the series and nothing else — it carries no severity meaning.
Ventilation
How much outdoor air a sealed building actually gets, why CO2 is the cheapest proxy for it, and what happens overnight in a closed bedroom.
In preparationMoisture
Dew point, cold surfaces and the difference between the humidity a room reports and the humidity at the wall behind the wardrobe.
In preparationMould
What suppression does and doesn't achieve, how long it lasts, and where the published evidence stops supporting what the industry sells.
In preparationSummer
Eight to ten months of mechanical cooling, what it does to a building, and the short windows when outdoor air is the better option.
In preparationPlants
What indoor plants measurably do to air in a room this size, and the arithmetic behind the claims made for them.
In preparationEvery figure carries its provenance, and every claim carries its source.
Charts show shape — the timing of a peak, the direction of change after we do work. Our devices are factory-calibrated without individual certificates, so a single absolute concentration quoted against a regulatory limit is not something we will put in front of you as a verdict.
Where a claim comes from a paper, the paper is cited with a link that resolves. Where our own data is shown, the figure states how many rooms, over what period, with what coverage. References & limits →
